In order to solve described problem and meet described object, the present invention proposes a kind of illuminator as the first embodiment, comprising:
The LED board (700) of-carrying LED (750,760,770,780); And
-optical sheet on described LED board, wherein said optical sheet is by according to from one to another predetermined orientation and the optical module (100 of registration, 100 ', 100 " ") make, each optical module (100, 100 ', 100 " ") comprise and be suitable for towards described LED (750, 760, 770, 780) at least one LED in and revise at least one optical element (150 of feature of the light that this at least one LED launches, 160, 170, 180), wherein said optical module (100, 100 ', 100 " base portion with limit ") is comprised further, described limit has mechanical fool proof element (111, 112, 121, 122, 131, 132, 141, 142), described mechanical fool proof element be suitable for preventing according to be different from described predetermined orientation from one to another orientation to described optical module (100, 100 ', 100 " ") position, and
Wherein said base portion has at least the first limit (110), Second Edge (130), 3rd limit (120) and the 4th limit (140), described first limit, Second Edge, 3rd limit and the 4th limit have the first mechanical fool proof element (111 respectively, 112), second mechanical fool proof element (131, 132), 3rd mechanical fool proof element (121, 122) the and four mechanical fool proof element (141, 142), wherein said first mechanical fool proof element (111, 112) and described second mechanical fool proof element (131, 132) be suitable for cooperatively interacting, and described 3rd mechanical fool proof element (121, 122) and described 4th mechanical fool proof element (141, 142) be suitable for cooperatively interacting, and wherein said first mechanical fool proof element (111,112) and described second mechanical fool proof element (131,132) can not coordinate with one of any in described 3rd mechanical fool proof element (121,122) and described 4th mechanical fool proof element (141,142).
By preventing the location of mistake of optical module, the foregoing problems during assembling optical module avoided by these mechanical fool proof elements: according to misalignment and/or the assembling of the fault orientation of optical module.
" truly " orientation of optical module corresponds to described " predetermined directed " and is confirmed as reaching predetermined illuminating effect.
First optical arrangement type (for it, these predetermined orientations can have certain importance) is the configuration with mutually different optical module or optical element.
As the first example, optical element can have concrete optical signature in the first section of illuminator, and other optical element can have other concrete optical signature in another section of illuminator, thus illuminator shows different optical feature on its optical sheet.Such as when illuminator is outdoor road illuminator, to design before bar or near " mixing " of the special lens of performance opticator and other lens of showing another optical profile away from bar may be interesting.The regularity that fool proof element causes is responsible for the overall light distribution of such system of correct location in optical sheet.
As the second example, colour mixture at optical element towards also can being interesting possibility when different colours, and the color exported from different optical element then on surface to be illuminated in optical sheet downstream mixed and upstream: the light exported from optical element therefore should be guided to perform this mixing, and therefore the Light distribation of optical element must be designed to meet this mixture of colours, and optical element must be correctly oriented---especially in asymmetrically distributed situation.Avoid to fool proof clear concept of the present invention some mistakes of these orientations during assembling process.Attention can be changed color by turning on and off or lighten or dim some LED.
Second optical arrangement type (for it, these predetermined orientations can have certain importance) is that wherein optical element has the configuration of asymmetric optical signature.
As the first example, optical element can be the lens or the prism that show asymmetric optical profile.Thus, the irradiation of illuminator significantly can change according to the orientation of optical module.The true orientation of these modules is therefore very important, and fool proof element reduces the fault orientation risk at industrial assembly process.
As the second example, optical element can have asymmetrical form (such as mark or asymmetric phosphor pattern), and the orientation of these forms on surface to be illuminated can have certain importance about required light effect.And fool proof element reduces the fault orientation risk at industrial assembly process again.
3rd optical arrangement type is (for it, these predetermined orientations can have certain importance) be that (such as illuminator can have optical element in the wherein optical design configuration of being made up of the some type optical element being dispersed throughout different optical module, this optical element has phosphor material, other is designed to colour mixture, other is designed to make the light of transmitting to be partial to concrete direction etc. or its a certain combination): also in this case, importantly prevent any location of mistake and the fault orientation of optical module.

By fool proof element is positioned optical module, fool proof (poka-yoke) only relates to optical module independent of the LED board used thereupon.Therefore, if the position of optical element corresponds to LED position, how the LED board that optical alignment uses thereupon is all completely freely with flexible.In addition, lower floor's configuration of each optical module and unmodified illuminator can easily be changed.
Alternatively, being designed at least partly in wherein said optical element (150,160,170,180) shows asymmetric optical profile, and described predetermined orientation is defined as making to consider that these asymmetric optical profile are to design predetermined light effect.
As previously noted, fool proof element of the present invention can especially must to show in the illuminator of identical asymmetric optical profile avoiding fault orientation and therefore to avoid mistake to irradiate useful at industrial assembly process, especially wherein all or some optical modules: once be that the first optical module selects fixed position, determine the location of subsequent optical module due to fool proof (or Poka-Yoke) design of optical module; Then all indivedual Light distribation of optical module is oriented on equidirectional.
Alternatively, wherein said LED board (700) by and the LED module of registration make, each LED module carries at least one LED (750,760,770,780) and is fixed to corresponding optical module (100,100 ', 100 " ").
